Results of the geomechanical modelling, coupled to flow modelling and micro-seismics simulations

Apply the numerical modelling approaches developed here and validate them against the results for the experimental investigation of fracking described in task 37 Experimental investigation of fracture propagation and fluid flow in fractures under anisotropic stress conditions and during hydrofracturing Most academic codes simulate fracturing through concentrated plastic strain along failure planes This approach may be adequate for ductile materials but not for the fragile failure conditions expected at hydraulic fracturing sites Therefore the second objective of this task is to extend and use existing codes to simulate fracture generation and to predict induced micro seismicity magnitude
